It's certainly safe to post a link to it here as a reply to an existing thread, but to make it a new thread on its own might be indescreet on your first day. The Viking Kitties (of which I'm one) have been pinged to your attention back on post #2 of this thread. You'll learn what the VK's are and what their purpose is over time.
My best advice is to sit back and enjoy. Find some ping lists you'd like to join and lurk for at least a day or two. All will become clear over time.
